There are 3 versions of the gpu: OC (higher clock freq), regular and silent (passive cooler).
As the Gearbox has 2 large ventilators, I'm thinking of going with the silent one, hoping it will cool the passive radiator enough.
Do you think it will be ok? Which variant of the card would you recommend based on experience? TIA
I would go with the regular card.
Overclocked cards can potentially drain too much power and shut the eGPU box off / cause instability.
Regular has fans - they will run quietly if cooling is sufficient, and it’s better to have fans and not need them than need them and not have them, in my opinion. Also the heatsink is designed for active cooling - tighter spacing.
Passive - I think heatsinks are designed a little differently for passive cards with wider spacing between the metal fins. I’m not sure if this is good for putting fans on them.
Also, I imagine that the passive card was not intended for use in a small, cramped box, but rather a large case where the heat can diffuse.
To play devil’s advocate with my own post, the new Mac Pro has fans at the front and passive heatsinks on its CPU and GPUs.
But to play devil’s advocate again, we have yet to see how that performs.
